Zane is a tricolored sheltie who lives on Beach Road. He's a little dog with a big voice, and every day during his walks, everyone in the neighborhood hears him barking. One neighbor thinks he's the happiest dog she's seen—and probably the yappiest.

Some of them don't like that very much, but most of them just shake their heads and laugh at the small dog with so much joy to spread. One day, when Zane and his owner walk by the art gallery in town, the sheltie begins barking a warning that something is wrong, and he refuses to move. What could be going on? His owner does some investigating, and soon she sees the gallery owner hurt on the floor. Thanks to Zane's barking, help soon arrives, and the little dog's friend is saved.

In this children's story, a small dog with a big voice and an outgoing personality becomes an unexpected hero in his neighborhood.
